Compliance with North American Standards

Compliance with International Standards

Compliance with the Specifications of Marine Classification Organizations

Compact® NS circuit breakers are built in accordance with Underwriters Laboratories Inc. UL 489 Standard and Canadian Standards Association CSA C22.2 No. 5.02 Standard. Circuit breakers, switches and their accessories, except where noted, are Listed under UL files E63335, E103740, E103955, and Certified under CSA files LR69561 and LR88980.

Compact NS circuit breakers and their accessories comply also with the following international standards:

• IEC 60947-1: general rules

• IEC 60947-2: circuit breakers

• IEC 60947-3: switches, disconnectors, switch disconnectors, etc.

In that these standards are applied in most countries, Compact circuit breakers and their accessories comply with European (EN 60947-1 and EN 60947-2) and the corresponding national standards:

• France NF

• Germany VDE

• U.K. BS

• Australia AS

• Italy CEI

Compact NS circuit breakers have been approved for marine application by the American Bureau of Shipping, Bureau Veritas, Lloyd’s Register of Shipping, Registro Italiano Navale, Germanischer Lloyd’s and Det Norske Veritas.

• IEC 68-2-30 damp heat

• IEC 68-2-2 dry heat

• IEC 68-2-11 salt spray

• IEC 68-2-1 low temperatures

Pollution Degree Compact NS circuit breakers are certified for operation in pollution degree III environments as defined

by IEC standard 947 (industrial environments).

Environmental Protection

Compact NS circuit breakers take into account concerns for environmental protection. Most components are recyclable and parts are marked as specified in applicable standards.

Suitability for Isolation (Positive Contact Indication)

06153037

Installation in Class II Switchboards

All Compact NS circuit breakers and switches are suitable for isolation as defined in the IEC 947-2 Standard:

• The isolation position corresponds to the O (OFF position).

• The operating handle cannot indicate the OFF position unless the contacts are open.

• Padlocks may not be installed unless the contacts are open

Installation of a rotary handle or a motor mechanism does not alter the functionality of the position indication system.

The isolation function is certified by tests guaranteeing:

• The mechanical reliability of the position indication system

• The absence of leakage currents

• Overvoltage withstand capacity between upstream and downstream connections

Circuit Breaker Marking

06153038

All Compact NS circuit breakers, even when fitted with a rotary handle or a motor mechanism, can be installed through the door of Class II IEC switchboards (as per IEC 664 Standard). Refer to circuit breaker installation instructions prior to installing circuit breaker.

Installation requires no special insulation because Compact NS circuit breakers provide Class II insulation between the front face and all internal circuits.

Section 2—General Characteristics

Suitability for Isolation (Positive Contact Indication)

The limiting capacity of a circuit breaker is its ability to limit short-circuit currents.

The exceptional limiting capacity of the Compact

Prospective Isc

t

®

NS line is due to the double break technique (rapid

natural repulsion of contacts and the appearance of two arc voltages in series with a steep wavefront).

The limiting capacity of the Compact NS line greatly reduces the forces created by fault currents in devices. The result is a major increase in breaking performance. In particular, the service breaking capacity Ics is equal to 100% of Icu.

The Ics value, defined by IEC 947-2, is guaranteed by tests comprising the following operations:

• Breaking a fault current equal to 100% of Icu three times consecutively

• Checking that the device continues to function normally

• Conduction of rated current without abnormal temperature rise

• Protection functions perform within the limits specified by the standard

• Suitability for isolation is not impaired

Longer Service

Current limiting circuit breakers greatly reduce the negative effects of short circuits on installations.

Life of Electrical Installations

Thermal Effects Less temperature rise in conductors, therefore longer service life for cables.

Mechanical Effects Reduced electrodynamic forces, therefore less risk of electrical contacts or busbars being distorted or

broken.

Electromagnetic Effects

Less disturbance for measuring devices located near electrical circuits.

Overload Indications (%Ir)

• LED (9) lights solid when current exceeds 0.9 Ir

• LED (9) flashes when current exceeds long-time threshold Ir

Fault Indications LEDs indicate the type of fault that caused tripping:

• Overload (LT protection) or abnormal component temperature (>Ir)

• Short-circuit (ST or instantaneous protection) (>Isd)

• Ground-fault (if earth-fault protection option is present) (>Ig)

• Microprocessor malfunction—both (>Ir) and (>Isd) LEDs go on, plus the (>Ig) LED, if the ground-

fault protection option is present

The LEDs are battery powered with spare batteries supplied in the adapter box. When a fault occurs, the LED indicating type of fault shuts off after approximately 10 minutes to conserve battery power. The fault data is stored in memory and the LED can be re-illuminated by pressing the battery/LED test button (9). The LED automatically goes off and memory is cleared when the circuit breaker is reset.

Zone-selective Interlocking (ZSI)

A number of circuit breakers are interconnected one after another by a pilot wire. In the event of a short-time or earth fault:

• If a given trip unit STR53UP detects the fault, it informs the upstream circuit breaker which applies

the set time delay

• If the trip unit STR53UP does not detect the fault, the upstream circuit breaker trips after its shortest

time delay

Opto-electronic Outputs

Communication (COM)

Possible Combinations

In this way, the fault is cleared rapidly by the nearest circuit breaker. In addition, thermal stresses on the circuits are minimized and time discrimination is maintained throughout the installation.

The use of opto-transistors ensures total isolation between the internal circuits of the trip unit and the circuits wired by the user.

Molded case switches are identical to molded case circuit breakers, except they are not equipped with trip units and sensors. Molded case switches open when the handle is switched to the OFF position or in response to an auxiliary tripping device such as a shunt trip or an undervoltage release.

These switches open instantaneously at a non-adjustable, factory preset, magnetic trip point calibrated to protect only the molded case switch itself. Magnetic settings:

• NSF150/250 A switches: 2000 A

• NSJ 400/600 A switches: 6000 A

These switches are suitable for use on a circuit capable of delivering not more than:

• 240 V: 100 kA for NSF switches and 150 kA for NSJ switches

• 480 V: 65 kA for NSF switches and 100 kA for NSJ switches

• 600 V (600Y/347 for NSF switches): 25 kA

Switches are Listed under UL file E103740 and Certified under CSA file LR 88980.

Section 7—Mounting Configurations

The plug-in configuration makes it possible to:

• Extract and/or rapidly replace the circuit breaker without having to touch connections

• Allow for addition of future circuits at a later date

When the circuit breaker is in the connected position, the primary voltage is fed through the circuit breaker by means of multiple finger disconnects. Control voltage of internal accessories is provided through secondary disconnects.

Parts of a Plug-in Configuration

Compact® circuit breaker (fixed mounted)

• Set of power and secondary disconnects that are added to the circuit breaker

• Plug-in base for mounting through a front panel or on rails

• Safety trip, to be installed on the circuit breaker, which causes automatic tripping if the circuit

breaker is ON before engaging or withdrawing it; the safety trip does not prevent circuit breaker operation, even when the circuit breaker is disconnected

• Mandatory short terminal shields

The plug-in mounting is Listed under UL file E113555 and Certified under CSA file LR 69561.

DRAWOUT MOUNTING

The chassis is made up of two side plates installed on the base and two other plates mounted on the circuit breaker.

AUXILIARY AND ALARM SWITCHES

06153101

Changeover Switches

Auxiliary switches provide remote information of the circuit breaker status and can thus be used for indications, electrical locking, relays, etc.

Functions • OF (open/closed): auxiliary switch—indicates position of the circuit breaker contacts

• SD (trip indication): bell alarm—indicates that the circuit breaker has tripped due to

— Overload — Short circuit — Ground fault — The operation of a shunt trip or undervoltage trip or the "push-to-trip" button which resets when

the circuit breaker is reset

• Operation of a plug-in base or chassis when attempting to withdraw the circuit breaker in ON

position; SDE (fault indication): indicates the circuit breaker has tripped due to an overload, short circuit or ground fault; resets when circuit breaker is reset

• CAM (early-make or early-break function): indicates the position of the rotary handle; used in

particular for advanced-opening safety trip devices

• Connected/disconnected: indicates the position of a drawout circuit breaker

• Switching of very low loads: all above auxiliary switches are also available in low-level versions

capable of switching very low loads (e.g., for controlling PLCs or electronic circuits)

Standards Auxiliary switches comply with UL 489, CSA C22.2 No. 5.1 and IEC 947-5 Standards. “Low-level"

switches are not UL Listed.

Installation • Functions OF, SD and SDE:

SHUNT TRIP AND UNDERVOLTAGE TRIP

A voltage release can be used to trip the circuit breaker via a control signal.

06153102

Undervoltage trip (MN)

• Trips circuit breaker when the control voltage drops below a tripping threshold

• Drops out between 35% and 70% of rated voltage

• Circuit breaker closing is possible only if the voltage exceeds 85% of rated voltage

• Permanent type

• If an overvoltage condition exists, operation of circuit breaker closing mechanism will not permit the

Shunt trip (MX) • Trips the circuit breaker when control voltage rises above 70% of its rated voltage

• Impulse type ≥ 20 ms or maintained control signals

• AC shunt trips can be operated at 55% of their rated voltage, making them suitable for ground-fault

protection when combined with a Class I ground-fault sensing element

Operation • The circuit breaker must be reset locally after being tripped by shunt trip or undervoltage trip

(MN or MX)

• MN or MX tripping has priority over manual (or motor operator) closing; in the presence of a

standing trip order such an action does not result in any closing, even temporarily, of the main

Section 13—Supplementary Technical Information

EFFECT OF HIGH TEMPERATURES

When the ambient temperature is greater than 40° C, overload protection characteristics are slightly modified. When determining tripping times using time/current curves, the Ir values corresponding to the thermal setting on the circuit breaker must be reduced using the coefficients below:

45° C 50° C 55° C 60° C 65° C 70° C

0.975 0.95 0.925 0.90 0.875 0.85

Example What is the tripping time for a TM200DP circuit breaker with a 400A fault current and an ambient

temperature of 40° C?

• Ir = 200 A

• I/Ir = 400/200 = 2

On the time/current curve, t = 100 s.

Consider the same conditions, except an ambient temperature of 65° C. What is the tripping time?

• Ir = 200 x 0.875 = 175 A

• I/Ir = 400/175 = 2.28

On the time/current curve,

≈ 65 s.

REFLEX TRIPPING

All Compact® NS circuit breakers and switches incorporate the exclusive reflex tripping system.

This extremely simple system breaks very high fault currents by mechanically tripping the device via a "piston" actuated directly by the pressure produced in the breaking units resulting from a short circuit.

For high short-circuit thermal withstand, this system provides a faster break. Reflex tripping curves are exclusively a function of the circuit breaker rating.

Dielectric After testing, the circuit breaker must withstand for one minute a voltage of 1000 V plus twice the rated

voltage between:

• Line and load terminals with circuit breaker in open, tripped and off positions

• Terminals of opposite polarity with circuit breaker closed

• Live parts and the overall enclosure with circuit breaker open and closed

Optional Tests

Tests On Accessories

• High available fault current—circuit breakers having passed all the standard tests may have the UL

Listing label applied at higher values than the standard; test sequence is as follows: — 200% calibration — Interrupting capacity: an opening operation followed by a close-open operation (O-and-CO) on

all poles are performed on the circuit breaker

The power factor over 20000 A shall be 0.15–0.2 lagging:

— Trip out at 250% — Dielectric at twice the rated test voltage

• 100% rated—circuit breakers having passed all the standard tests may have the UL Listing label

applied to use the circuit breaker in an enclosure when carrying 100% of its maximum rating

The circuit breaker is submitted to additional temperature tests performed as standard tests, except that the circuit breaker is installed in an enclosure. The dimensions and possible ventilations shall be recorded and shall be marked on the circuit breaker.

Shunt trip and Undervoltage Trip—these devices are submitted to temperature, overvoltage, operation, endurance and dielectric tests.

Overvoltage Test—the device must be capable of withstanding 110% of its rated voltage continuously without damage (this test does not apply to a shunt trip with an "a" contact connected in series).

Operation:

Shunt Trip—must operate at 75% of its rated voltage (except shunt trip devices for use with groundfault protection shall operate at 55%).

Undervoltage Trip—must trip the circuit breaker when the voltage is less than 35% and may trip the circuit breaker between 35 and 70% of its rated voltage and shall pick-up and seal when the voltage is at 85% or more of its rated voltage.

Endurance—the device must be capable of performing successfully for 10% of the number of "with current" operations of the circuit breaker.

Auxiliary and Alarm Switches—auxiliary and alarm switches must be submitted to temperature, overload, endurance and dielectric tests.

Overload Test—the test consists of fifty operations making and breaking 150% of rated current at rated voltage, with a 75–80% power factor in ac and non-inductive load in dc.

Endurance—the switch must make and break its rated current at rated voltage, with a 75–80% power factor in ac, and non-inductive load in dc for 100% of the number of operations "with current" for auxiliary switches, and 10% of this number for alarm switches.

Motor Operator—the motor operator shall perform the number of "without current" operations indicated for the circuit breaker endurance tests. The first 25 operations shall be conducted at 85% of the motor operator voltage rating. The circuit breaker is to be tripped during these tests. The next 25 operations shall be conducted at 110% of the motor operator voltage rating. The balance shall be completed at rated voltage without tripping the circuit breaker.

Section 13—Supplementary Technical Information

IEC 947-2 TEST PROCEDURE

Standard Tests Consisting of seven parts, the IEC 947 Standard applies to all low-voltage equipment designed for

industrial application.

Three documents are to be consulted for circuit breakers and switches:

• IEC 947-1: general regulations

• IEC 947-2: circuit breakers

• IEC 947-3: switches

Two Categories of Devices

Breaking Capacity

Ultimate Breaking Capacity: Icu

Breaking Performance During Operation: Ics

The IEC 947-1 standard defines two categories of devices:

• Category A—devices not specifically designed to carry out chronometric selectivity

• Category B—devices specifically designed to carry out chronometric selectivity; these circuit

breakers possess a compulsory additional characteristic: short-time withstand (Icw)

Icu is the value to be taken into account when calculating an installation. The rule remains: Icu > Icc (maximum fault current of the installation).

This characteristic indicates the ability of the device to eliminate short-circuit currents less than Icc and with a greater likelihood of occurring, generally near the application. Ics is expressed in % of Icu (values retained by the standard IEC 25-50-75-100% of Icu). This test sequence designed to check the Ics performance, groups together on the same device, following the breaking test (O-CO-CO, see page

72), certain checks such as:

• Temperature rise under In

• Calibration at 1.45 In

• Leakage current (for devices suitable for disconnection)

The leakage current should not exceed 2 mA under the application voltage (0.5 mA when new). These checks ensure that the device is able to carry out all its functions after elimination of a fault of Ics value and to be put back in operation; hence the notion of breaking power performance during operation Ics.

Isolation

Function Recognition and definition of the disconnection capacity for industrial low-voltage equipment:

Until recently, circuit breaker standards have established no regulations concerning the isolation function. Only the installation standards provided some rather vague information. The IEC 947 standard takes this function into account. In the "general regulations" section, it clearly states:

• The manufacturing regulation

• The tests to be performed

The circuit breaker standard should define the manner in which the tests are to be performed (under study). The manufacturing regulations state, for example:

• Both the isolation and the inner contact distances (open > 8 mm)

• A device indicating the true position of the contacts (operating handle if representative of the state

of all the contacts)

• When a "locked" position is provided, this should only be possible with "open" contacts

The tests to be performed are as follow:

• Shock wave voltage strength (Uimp)

• Measurement of leakage current—under 110% of the device application voltage, maximum leakage

currents proposed per pole: — 0.5 mA new device — 2 mA device after Ics — 6 mA device after Icu or after endurance tests, representative of the "end of service life."

HAZARD OF EQUIPMENT DAMAGE

Molded case circuit breakers contain factory-sealed and calibrated elements. The seal must not be broken and the circuit breaker must not be tampered with. Molded case circuit breakers should not be field adjusted or repaired. In the case of a malfunction, the circuit breaker should be replaced or inspected at the Schneider Electric factory, or by an authorized representative.

Failure to follow this instruction can result in equipment damage.

DANGER

CAUTION

Merlin Gerin circuit breakers are designed to be maintenance-free. However, all equipment with moving parts requires periodic inspection to ensure optimum performance and reliability. It is recommended that the circuit breakers be routinely inspected six months after installation, followed by annual inspection. Intervals can vary depending on particular usages and environments.

Inspection of Terminals

• Connections to circuit breaker terminals should be inspected. If there is discoloration due to

overheating, the connections should be disassembled and the surface cleaned before reinstallation. It is essential that electrical connections be made carefully in order to prevent overheating.

• Check for terminal tightness.

Cleaning Remove dust and dirt that have accumulated on the circuit breaker surface and terminals.

Mechanical Checks

Even over long periods of time, circuit breakers are not often required to operate on overload or shortcircuit conditions. Therefore it is essential to operate the circuit breaker periodically. To trip the circuit breaker, push the push-to-trip button.

Insulation Resistance Tests

When a circuit breaker is subjected to severe operating conditions, an insulation resistance test should be performed as indicated in NEMA standard publication No. AB4-1996. An insulation resistance test is used to determine the quality of the insulation between phases and phase-to-ground. The resistance test is made with a dc voltage higher than the rated voltage to determine the actual resistance of the insulation.

The most common testing method employs a "megger" type instrument. A 1000 V instrument will provide a more reliable test because it is capable of detecting tracking on insulated surfaces. Resistance values below one megohm are unsafe and should be investigated. An insulation test should be made:

• Between line and load terminals of individual poles with the circuit breaker contacts open

• Between adjacent poles and from poles to the metallic supporting structure with the circuit breaker

contacts closed. The latter test may be done with the circuit breaker in place after the line and load conductors have been removed, or with the circuit breaker bolted to a metallic base which simulates the in-service mounting.

Electrical Tests These tests require equipment for conducting pole resistance, overcurrent and instantaneous tripping,

in accordance with NEMA Standard publication No. AB4. They are not within the scope of normal field operation.
